QuadroX is a program that really requires you to think outside the box. Its an interesting game thats roughly similar to one you might have played as a very young child. The object is to fill a square with pieces of different shapes. Once youre able to create a perfect square, you move on to a more difficult level. Its a geometry teachers dream. The full version of QuadroX covers three episodes with 30 levels each. This shareware version includes levels from the first episode.
